If you are getting microwave ovens. Things are gonna change soon.
We (people in general) are getting rid of the older ovens with 2 coils of Copper in the transformers and buying more newer ovens with 'Invertor tec' in them (Invertor tec means 100gms of Copper wire rather than 2 Lbs) and cheaper ovens with one Copper & one Ali coil in the windings, maybe even two Ali windings....
Most microwaves stop because someone opened the oven door while it was still going.
While its still going, theres a larger amount of power going thru the safety switches, because of the higer power, thers a bigger arc, and that burns the contacts shut, or open.
That will blow the microwaves main fuse, stopping it from working. Thats when most people throw them away.
So, check to see if its any good & can be resold, then check if the safety switches are operating properly, then replace them & see if it works. If it works - sell it!
Most of the time you have to replace all of the switches at the same time, as the contacts burn out at the same rate.

Look at the spinners in the dishwasher. They wear out in the centre. I have made a post a few days ago about it. Check that as the spinner seems to be the first thing that wears out.
